Self-adhesive capacitive sensor head simplifies level detection
Balluff A self-adhesive, capacitive sensor head with IP 64 protection for non-contact, continuous level detection on non-conductive vessel or pipe outer walls made of glass, plastic or ceramic is available from Balluff.
The flexible sensor head, which has a maximum detection range of 850 mm in length, can be individually trimmed to length (minimum 108 mm) and attached to container walls without the need for additional accessories using the integrated adhesive surface.
For polar, aqueous media the wall thickness can be between 2mm and 6mm, or up to 2mm for non-conductive media such as oil or bulk materials. The sensor is designed for use with the company's type BAE sensor amplifiers.
The optional amplifier allows levels to be continually detected over the entire measuring range as analogue values (0-10 V, 4-20 mA) or via IO-Link or as minimum or maximum value exceeding.
Both the IO-Link and the analogue convenience amplifier are said to offer a variety of versatile setting possibilities.
